UG-120: Evaluating the ADM3251E Isolated RS-232 Transceiver
User guide for evaluating the ADM3251E, a 2.5 kV fully isolated RS-232 transceiver with integrated power and data isolation.
Overview
The UG-120 user guide provides instructions for the ADM3251E evaluation board, a 2-layer PCB designed for testing the ADM3251E RS-232 transceiver. The ADM3251E features 2.5 kV fully isolated power and data, operating from a 5 V supply. The board includes screw terminal blocks for power and signal connections, test points for all signals, and a patchwork area for through-hole components. The document provides the full evaluation board schematic, printed circuit board layout, and a complete bill of materials including the ADM3251EARWZ transceiver.
Use Cases
- Isolated RS-232 communication
- High voltage signal protection
- Industrial serial interface evaluation
- Integrated power and data isolation testing
